Body shape (shape guide): elongated.
Meso- and bathypelagic at 700-1830 m (Ref. 58302). Probably swift swimmers, which can avoid nets, captured singly or in small groups (Ref. 6692). Carnivorous, feed on squids and pelagic fishes (Ref. 6692). Oviparous and are synchronous hermaphrodites (Ref. 84733).
